IMPROVEMENT IN UMBRELLA-FRAM ES.

Specification forming part of Letters Patent No. 217,533, dated July 15,1879; application filed April 8, 1879; patented in England, August 2,1878.

of that kind which do not have catches to hold them open and closed.

In order that the catches commonly employed in connection withumbrellas, parasols, an d sun-shades to keep them open and closed may bedispensed with, and also in order to strengthen the frame, I employ anadditional or intermediate runner, sliding upon the stick between theordinary runner which receives the ends of the stretchers and the topnotch to which the ends of the ribs are jointed. This interme diaterunner I connect by links to the stretchers. The stretchers have bitsfixed upon them at some distance from their inner ends to receive thejoint-pins for connecting the links. I sometimes employ two links inconnection with each stretcher, one on either side of it, so that whenthe umbrella, parasol, or sunshade is closed the stretcher may lie closeto the stick between the two links; also, to keep the stretchers in thisposition when the um-' brella, parasol, or sun-shade is closed, I fix aspring to each stretcher at a point some distance away from the bit towhich the links are jointed. This spring bears upon a crossbar, whichconnects the two links together at a short distance from the joint, andtends to press the cross-bar toward the stretch er, and so to make thestretcher and the links lie parallel the one to the other, which isapproximately being then in contact with the top notch.

In order that my said invention may be most fully understood and readilycarried into effect, I will proceed to describe the drawings hereuntoannexed.

Referring to the drawings, Figure 1 is a section of the frame of anumbrella zonstructed according to my invention.

Ais a portion of the stick. B is the top notch, fixed to the stick nearits end and receiving the inner ends of the ribs G (J, as is usual. D isthe ordinary runner, capable of sliding along the stick, and the innerends of the stretchers E are jointed to it. The outer ends of thestretchers are also jointed to the ribs in the ordinary way, and as isseen in Fig. 1.

F is the intermediate runner, which I place upon the stick between theordinary runner D and the top notch, B. G G are the links by which Iconnect the intermediate runner with the stretchers. I employ, bypreference, two of these links for each stretcher, so that the links lieon either side of the stretchers.

E E are bits fixed upon the stretchers to receive the pins by which thelinks G are jointed to them. These bits are applied in the same way asthe bits on the ribs are. usually H H are cross-bars connecting thelinks of each pair. The way in which these cross-bars are applied isrepresented in the cross-section, Fig. 2, which is drawn to an enlargedscale.

I I are springs fixed to the stretchers, and which press upon thecross-bars H. The way in which the springs I are fixed in their placesupon the stretchers is shown by the cross-section, Fig. 3, which also isdrawn to an enlarged scale.

Fig. 4 is a side View of a portion of the stick of the umbrella, andwith it there is shown the outer end of one of the ribs 0; also theordinary runner D, the intermediate runner, F, and

two of the links G, connecting the intermediate runner with one of thestretchers. The stretcher itself is not seen, as it lies beneath therib. All theparts in this figure are in the positions which they occupywhen the umbrella is closed.

Fig. 5 shows the head of the intermediate runner and the ends of thelinks G, jointed to it in a similar manner to that in which the ribs arejointed to the top notch and the stretehers to the ordinary runner.

Fig. 6 is a plan of a port-ion of one of the stretchers, with the pairof links G jointed to it, their cross-barH, and the spring I, fixed tothe stretcher and pressing upon the cross-bar.

The pressure of the springs upon the crossbrella is opened it fills theinterval between the top notchand the ordinary runner D, as is seen inFig. 1.

The cover of silk or other fabric is not shown in the drawings. It isapplied in the usual way.

Sun-shades and parasols may be similarly constructed. 7

Fig. 7 shows another arrangement for carrying out my invention.

This compels them,

E is one of the stretchers, and G is a single link connecting thisstretcher with the intermediate runner, F. J J are two parallel blades,which take the place of the spring 1 in the arrangement first described.The blades J lie in the trough-like hollow of the stretcher E, and aresecured by a rivet, J The link G is connected with the blades J by apinpoint at G", and the end of the link projects so far beyond thejoint-pin G that it bears against the stretcher, and the movement of theparts in opening and closing the umbrella, parasol, or sun-shade causesdeflections of the parts, from which a spring-like action results, as inthe arrangement already described.

Having thus described the nature of my said invention and the manner ofperforming the same, I would have it understood that I claim- 1. Thecombination of the intermediate runner, F, the links G, and thestretchers, arranged to operate substantially as described.

2. The combination of theintermediate runner, F, the links G, thestretchers, and the spring-connection between the. links and thestretchers, whereby the umbrella tends to keep open when open, and tokeep shut when shut, substantially as set forth.
